Wi-Fi 6 is coming to a router near you

The Wi-Fi alliance has changed the naming
scheme for Wi-Fi standards, abandoning the 802.11 designations for
simpler names like Wi-Fi 6, Wi-Fi 5, Wi-Fi 4, etc., but that may gloss
over some of the finer points of the old IEEE system.

Just when we were all getting used to the IEEE 802.11 Wi-Fi nomenclature
that differentiates between generations of the technology, the
industry’s Wi-Fi Alliance has gone and made it simpler and more
digestible for the user on the street.

As a result, starting this month what we know as 802.11ax is officially called Wi-Fi 6.

The new, vastly simplified system also means that 802.11ac is now Wi-Fi 5, and 802.11n is Wi-Fi 4. The idea, according to the Wi-Fi Alliance, is to make matching endpoint and router capabilities a simpler matter for the rank-and-file user of Wi-Fi technology.

Think of it as the unlicensed equivalent to the various Gs – 3G, 4G, 5G
– that the cellular data carriers have rolled out over the years –
broad descriptors of the generation of connectivity tech that it’s in
place on a given device, not specific technical specifications.

What is Wi-Fi 6 good for?

The
basic technology behind Wi-Fi 6, which is still known as 802.11ax on
the technical side, promises major advances beyond just higher data
rates, including better performance in dense radio environments and
higher power efficiency.

Wi-Fi 6 is also seen as a possible
communications method for internet-of-things (IoT) devices that have low
power capabilities and limited battery life. Thanks to a feature called
target wake time, Wi-Fi 6 IoT devices can shut down their Wi-Fi
connections most of the time and connect only briefly as scheduled in
order to transmit data they’ve gathered since the last time, thus
extending battery life.

Farpoint Group principal and Network World contributor Craig Mathias said that, given the degree to which consumerization is the driving force even behind enterprise IT these days, the re-naming is probably a step in the right direction, but that doesn’t mean that simply labeling 802.11ax as Wi-Fi 6 tells the whole story.

“Saying,
for example, that a given product is ‘Wi-Fi 6’ just specifies which
generation it belongs to, and very little else,” he said. “By analogy,
one can purchase a 2019 Ford Edge. But there are also SE, SEL, Titanium,
and ST models, and numerous options for each of these trim levels. So
saying one has a Ford Edge isn’t really very descriptive at all.”

A
bigger potential issue, Mathias added, is that presenting different
Wi-Fi technologies via a simple sequential naming convention can mislead
users. 802.11ad and ay are 60GHz standards, with vastly different
characteristics and capabilities than 2.4GHz and 5GHz systems. Simply
calling them “Wi-Fi 7” makes them sound like the next generation of the
same technology, not something that’s fundamentally designed to
accomplish different tasks.

“A number of potential issues arise if linear numbering is taken to imply ‘better,’” he said.

The
Wi-Fi Alliance says that vendors will be able to incorporate the new
naming scheme in their user interfaces. So as mobile users move from
access point to access point, their screens will use the new numbering
system show the standard that was used to establish the current
connection.

The new terminology will also be applied to the Wi-Fi
Alliance’s certification program for wireless products. So, for example,
starting next year if a product meets the 802.11ax standard it will
receive a Wi-Fi CERTIFIED 6 designation.
